#Step 1
Because the column name has a & sign in the name i will first have to determine the system name of this column.
To do that go to the list settings and edit the desired column. In the URL you can see what the internal system name for this column is. In our case it is: Events_x0020_journals.

#Step 2

Open up SharePoint Central Admin and go to the Manage service applications page.

#Step 3

Open the Search Service Application page

#Step 4

Managed properties can be found in the Search Schema section

#Step 5

First lookup the name for the list column. This will have the prefix of ows_
Click on Crawled Properties then enter the name (or a part of the name) of the column and hit Enter. You can see that the column is found and that the name is: ows_Events_x0020_Journals.

Clicking on Managed Properties will take you to the screen where you can create a new one.

#Step 6

Click on New Managed Property

#Step 7

Enter a name for the new property, select the type and check the boxes for the main characteristics.

Read the text next to the checkboxes to help you decide if you need that functionality.

#Step 8

Scroll down to Mappings to add a mapping to for this new property.

#Step 9

First enter the column name we found in step 1, then click find. Select the right property and hit OK.

This will create the new Managed Property

#Step 10

Type the name in the Filter field and hit Enter to check if the property exists.

#Step 11

To wrap things up you will have to start a full crawl before the new Managed Property is available. Goto the Content Sources and click on Start Full Crawl in the drop down menu for the content source where you want to use the new Managed Property.

#That’s it.
